Abstract

A trommel assembly includes a trommel frame, a plurality of screen panels mounted to the trommel frame to define a material processing channel configured for receipt of screening material, and a gate assembly mounted to the plurality of screen panels. The gate assembly extends into the material processing channel along a radial direction and includes a plurality of circumferential dams that extend substantially along a circumferential direction and are spaced apart along an axial direction to define a plurality of screening stages. The gate assembly further includes a plurality of transfer gates extending at a transfer angle relative to the circumferential direction between adjacent dams of the plurality of circumferential dams, wherein the plurality of transfer gates connect the plurality of screening stages such that rotating the trommel assembly advances the screening material through the material processing channel.
